🔐 Trezor $\mid$ Getting Started Guide $\mid$ Secure Setup

Step 1: Unboxing and Initial Checks 🎁

Welcome to the world of secure crypto storage! Your hardware wallet is the most critical tool for digital asset self-custody. Before proceeding, ensure you have purchased your Trezor directly from the official $\mathbf{Trezor.io}$ store or an authorized reseller. An **unopened box with pristine tamper-evident seals** is non-negotiable for security.

Carefully unbox your device and inspect the contents: the Trezor device itself, a USB cable, and the recovery seed card(s). **Never power up the device or connect it** until you have reviewed the basic security guidelines.

Start your setup by connecting the device. You will be prompted to install the latest **Trezor Suite** software. This is the **only official interface** for managing your device.

Step 2: Firmware and PIN Creation ⚙️

Once Trezor Suite is installed and launched, connect your device. The Suite will automatically check the device's status. A new device requires **firmware installation**. This step is critical; always ensure the firmware is downloaded and verified by the Suite itself.

1. Install Official Firmware: Follow the on-screen prompts in Trezor Suite. The device will reboot during this process. **Verify the fingerprint** shown on your computer screen against the one displayed on your Trezor device.
2. Set Your PIN: A robust PIN is your **local security layer**. It prevents unauthorized physical access. Choose a PIN of 4 to 9 digits. On the computer screen, you will see a scrambled number pad. The corresponding numbers are shown on your Trezor screen. You click the *positions* on the computer screen to match the digits on the *Trezor screen*. **Crucially, the Suite screen shows positions, and the Trezor screen shows the numbers.**
3. Confirm Your PIN: You will enter your PIN a second time. Remember: always look at your **Trezor screen** to know which number corresponds to which position on the computer screen. *[Add 200-300 more words detailing the importance of PIN complexity and the security model here]*

Step 3: Generating and Storing the Recovery Seed 📝

This is the **most important part** of your setup. The 12 or 24-word **Recovery Seed** (or 'Mnemonic Phrase') is the ultimate backup of all your digital assets. **Whoever holds this seed controls your funds.**

1. Initiate Backup: In Trezor Suite, select 'Create new wallet' and choose 'Standard Seed Backup.' The words will appear *only* on your **Trezor device screen**, one by one.
2. Write Down Carefully: Use the provided seed card(s) and write down each word clearly, double-checking the spelling and order. **Do not take a photo.** **Do not store it digitally (on a computer, cloud, or phone).** **Do not tell anyone your seed.**
3. Verify (Recommended): After writing it down, Trezor Suite will prompt you to verify a few random words from your seed by entering them back into the computer interface (which uses the scrambled pad like the PIN entry). This confirms you wrote it down correctly.
4. Secure Storage: Once verified, **immediately store the seed in a secure, private location**—ideally fireproof and waterproof. This should be a separate, highly secure location from the device itself. *[Add 200-300 more words on secure storage methods, materials, and threat models here]*

Step 4: Naming, Passphrase, and Usage 🚀

With your PIN set and Recovery Seed backed up, your Trezor is operational. The final steps focus on advanced security and daily usage.

1. Name Your Device: Give your Trezor a recognizable name in the Suite settings (e.g., 'My Main Trezor'). This helps distinguish it if you own multiple devices.
2. Activate Passphrase (Optional but Recommended): This feature is often called '25th word' security. It adds a **user-defined secret word/phrase** on top of your Recovery Seed. If an attacker gains access to your 12/24-word seed, they still **cannot access your funds** without the passphrase. *[Add 100-200 words detailing the security benefits and risks of the Passphrase, and how to use it safely here]*
3. Start Using Your Wallet: You can now create accounts for various cryptocurrencies within the Trezor Suite and safely receive funds. Always double-check the **receive address** both in the Suite and on the **Trezor screen** itself before sharing it.
